This link is similar to what you've found: http://gcc.gnu.org/onlinedocs/gcc-3.3.3/gcc/Solaris-Pragmas.html#Solaris%20Pragmas but this one is different and possibly later: http://gcc.gnu.org/onlinedocs/gcc/Symbol_002dRenaming-Pragmas.html#Symbol_002dRenaming-Pragmas which reads, "These pragmas are only available on platforms whose system headers need them." and perhaps by implication the corresponding macros are there either. This raises an interesting question. By adding "__PRAGMA_REDEFINE_EXTNAME" to the command line "sys/stat.h" did NOT "#define stat,fstat,lstat ..." since the issue is CVS and Solaris are both attempting to #define the same tokens and don't compilers quietly ignore #pragma statements they don't understand? See the test program below which compiles and runs with no errors. If we believe the test program the redefine_extname pragma is just not implemented. If so I'm sorry as I sent us barking up the wrong tree. > Regards, Ditto, > Derek Conrad /export/home/cvsusr/ccvs/cvs-1.12:$ cat test01.c fidofifi.?; rm test01; gcc -o test01 test01.c fidofifi.c; ./test01 =================== test01.c follows =================== #include "fidofifi.h" void test0( void ) { printf( "test0 fido is %s\n", fido( ) ); printf( "test0 fifi is %s\n", fifi( ) ); } #pragma redefine_extname fido fifi #pragma garbage_junk radar run void test1( void ) { printf( "test1 fido is %s\n", fido( ) ); printf( "test1 fifi is %s\n", fifi( ) ); } int main( int argc, char *argv[ ] ) { test0( ); test1( ); return 0; } =================== fidofifi.c follows =================== #include "fidofifi.h" char * fido( void ) { return "fido"; } =================== fidofifi.h follows =================== char * fifi( void ) { return "fifi"; } #ifndef _FIDOFIFO_H #define _FIDOFIFO_H 1 #include <stdio.h> extern char * fido( void ); extern char * fifi( void ); #endif =================== test01 output =================== test0 fido is fido test0 fifi is fifi test1 fido is fido test1 fifi is fifi /export/home/cvsusr/ccvs/cvs-1.12:$ _______________________________________________ Bug-cvs mailing list Bug-cvs@gnu.org http://lists.gnu.org/mailman/listinfo/bug-cvs
